Baby crooner upstages street performer

A street singer would always expect applause and clinking of coins after every performance, but a Polish performer found himself in a duet with a baby instead.

The male soprano captivated the crowd as he sang an opera song in his melodious voice in Cracow, Poland. Little did he know that the baby, strapped in a stroller, behind him was ready to steal the limelight.

The baby joined and broke out into her own rendition of the classic hymn, even trying to top the man's pitch. She mouthed totally different lyrics of the song, yet tried to be in sync by pausing whenever the man stops singing. Even after the man ended his musical piece, the child still continued and pulled off a sweet harmonic close.

The singing duo drew applause and even more cash from their audience. Since its posting on YouTube, their video has received nearly 600,000 views.
